High Polished Circular 99 Alumina Ceramic Block

High Polished Circular 99 Alumina Ceramic Block

99% Alumina Ceramic Blocks are high-performance ceramic materials known for their exceptional mechanical properties, wear resistance, high-temperature endurance, and corrosion resistance. Made from aluminum oxide with a purity level of 99%, these blocks exhibit high hardness, low thermal conductivity, and excellent electrical insulation characteristics. They are widely used in various industries such as electronics, aerospace, automotive, and medical fields for applications requiring precision and durability. The high purity of alumina ensures the material's purity and consistency, making it ideal for demanding environments and critical applications.

The high purity of 99% alumina ceramic ensures low levels of impurities, providing a chemically inert surface that is ideal for applications where contamination must be avoided. Their high mechanical strength and resistance to abrasion make them a durable choice for industrial applications, including mechanical components and wear parts. Additionally, these plates are resistant to corrosion, further enhancing their longevity and reliability in various applications.
